General description
Nα-Benzoyl-DL-arginine 4-nitroanilide hydrochloride (DL-BAPNA) is a chromogenic substrate for proteolytic enzymes such as trypsin, amidase, and balterobin. Hydrolysis of DL-BAPNA at the bond between the arginine and the p-nitroaniline moieties releases the chromophore p-nitroaniline, which can be detected by colorimetric analysis.
A chromogenic trypsin substrate.
Application
Nα-Benzoyl-DL-arginine 4-nitroanilide hydrochloride has been used as a substrate for trypsin and elastase in enzyme analysis.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.

Why do the bottoms of the vials/bottles of product B4875-100MG (Nα-Benzoyl-DL-arginine 4-nitroanilide hydrochloride) appear to have no bottom? How is the product contained within the vials despite this unusual appearance? Is this a packaging defect?
